# Buy AI credits

> AI credits pay for the models behind chat, Build mode, Studio, Alchemy and the inference API. Here is what they cost, where to see them and how to top up.

Every reply from a model costs a little, and AI credits are how you pay for it. They are a separate balance from your trading funds, so buying credits never moves money out of a venue, and running low on credits never touches your positions.

## What credits pay for

Credits are spent whenever a model does work for you:

* replies in [Chat](https://docs.openfinance.tech/product/chat.md) and builds in [Build mode](https://docs.openfinance.tech/product/build-mode.md),
* images in [Studio](https://docs.openfinance.tech/product/studio.md),
* runs in [Alchemy](https://docs.openfinance.tech/alchemy/overview.md),
* calls to the [inference API](https://docs.openfinance.tech/inference/overview.md) from your own code.

The model you pick sets the price. The model picker shows each model's price tier, so you can choose a lighter model for quick questions. See [Models and AI credits](https://docs.openfinance.tech/product/models-and-credits.md) for the details.

## What they cost

You buy credits with stablecoins from your own wallet. One dollar comes to about 10 credits, and the Fund AI credits sheet shows the estimate (for example "≈ 500 credits") before you pay, so there are no surprises.
